CLAMPING- DEVICE FOR USE WITH RODS AND THE LIKE.

To all whom it may concern:

,Be it known that 1, JOHN REGINALD BROWN, a subject of the King ofEngland, residing at 9 Melville road, Brighton, in the county of Sussex,England, ironmongers assistant, have invented certain new and usefulImprovements in Clamping Devices for Use with Rods and the like, ofwhich the following is a specification.

This invention relates to an improved clamping device for use with rodsand the like which device permits the rod to he slid with respectthereto, to be turned in any direction with respect to the axis of thedevice and to be clamped in any required p0 sition. H

The device is more particularly app cable for use for locking the staysof case' ment and other windows, but may also be adapted for otherpurposes.

The device comprises a base plate or its equivalent carrying a memberrotatable with respect thereto in or through which member the rod or thelike to be clamped slides, and a screw or other equivalent means adaptedto prevent the rod sliding with respect to the device and also toprevent the rotatable portion of the device rotating with respect to thebase plate.

In the preferred method of applying my invention to a clamp for acasement stay I provide a base plate which is adapted to be attached byscrews or the like to the casement frame. This base plate is furnishedwith a central hole having a downwardly beveled or conical edge. I alsoprovide a bolt having a taper head adapted to fit within the conicalhole just mentioned and having in the shank an elongated hole ofsufficient size for the casement stay to pass through. The said boltisreduced and provided at the top with a screw threaded portion for thereception of a milled nut or the like. Adapted to fit over the bolt is acollar furnished with a substantially semi-circular ,groove, adapted toreceive the lower half of the casement stay and another collar isprovided with a similar substantially semicircular groove adapted to fitover the upper portion of the easement stay. The milled nut or the likeis screwed on to the screw threaded portion of the bolt and bears uponthe uppermost collar.

It will be seen that when the milled nut is loosened the easement staycan be slid longitudinally and as the easement opens or Specification ofLetters Patent.

closes the part of the device through which the stay passes is enabledto turn with respect to the base plate, thus accommodating itself to theposition the easement is in the In order that my said invention may bebetter understood, 1 will now proceed to described the same withreference to the drawing accompanying this specification in which:

Figure 1 is a perspective view ment with my invention applied thereto;Fig. 2 is an enlarged side elevation of the casement stay and clampingdevice; Fig. 3 Fig. 4 is an enlarged sec- Fig. 5 is another section atright angles to the section at Fig. 4. Fig. 6 is a section on the line AB Fig. 4. Figs. 7 and 8 are details hereinafter referred to.

In the drawing a is the frame of a casement window to which isattachedthe ordi nary swivel bracket 6, to which the stay 0 is pivoted.Attached to the'casement frame 6 is the clamping device constituting thesubject matter of the invention. This comprises a base plate 7 providedwith screw holes for attaching it to the casement frame 0 and having acentral hole provided with a beveled or conical edge 9.

it is a bolt provided with a conical head 7c, of such size as to fitwithin the conical hole 9, and furnished with an elongated slot m ofsufficient size to enable the easement stay (.2 to slide easilytherethrough. The bolt is reduced at the top and provided with a screwthreaded portion n.

p is a circular collar,provided with grooves g diametrically oppositeone another in its walls, such grooves being slightly less than asemi-circle. r is another collar show-n detached at Fig. 7 and alsofurnished with a similar groove 8 in diametrically opposite positions.This collar 1* is reduced at the top and provided with a plain holeadapted to come loosely around the screw n. z, is a milled nut adaptedto screw on to such screw 12. and bear upon the top of the collar T.

It will be seen that when the milled nut 25 is screwed home it causesthe screw n to of a casewas" , screw is screwed l to be understood thathole 9', thus preventlng be pulled upward exerting an upon the bolt h.This causes to come into upward pull the head tight contact with theconical the rotationof the bolt with respect to the base plate f. At thesame time the milled nut presses the upper collar downward and causesthe stay 0 to be clamped between the grooved portions in such collar andin the lower collar 1), thus preventing any longitudinal slidingmovement of the said stay. As soon as the milled nut is loosened thebolt is enabled to rotate upon its axis and the stay can also slidebetween the loosened groove portions-0f the collars. i It will be seenthat when the clamping home, it presses on the u or surface of thecasement stay and binds it tightly against any sliding action. At thesame time an upwar pull is exerted upon the part 4 causing the head ordisk 6 to bind against the under surface of the recessed portion of thebase plate,thus preventing any rotation of the part about its own axis.

It will be understood that the saddle piece 9 can be dispensed with ifdesired, especially in the case Where the easement stay is ofrectangular section. In other cases an upper saddle piece may befurnished or both an upper and a lower piece.

As previously remarked the device may be adapted for other purposesbesides locking the stays of casement windows. It is the particularmethods of constructing the device according to my invention describedin detail are given merely by Way of example as the construction may bevaried considerably to k departing from adapt the-device to varioususes, without the principle of my inven- What I claim and desire tosecure by Letters Patent of the-United States of America is 1 r 1. In adevice of the class described, a casement rod or stay, locking meanspreventing the longitudinal movement of said stay, comprising a collaradapted to fit the lower portion of the easement rod, a second collaradapted to fit said rod above the first collar,
